PUSH CAR.

Application filed July 30,

The invention relates to a childs toy vehicle. Safety againstoverturning is obtained by employing three wheels, the forward wheelsupporting a vertical member formed preferably to imitate the head of ahorse. The two rear wheels support the main body portion and there is apivot-ed connection between the forward guiding portion of the vehicleand the main body portion, for steering purposes.

The rear wheels are rigid with the rear axle member which rotates inbearings in sideframe supporting members. Hinged to the horizontal bodymember of the vehicle and behind the point of pivot is a seat element.Means carried by the rear axle drive means connected to a forwardcountershaft element. The forward shaft is provided with a crank elementcarrying a rod, said rod being driven in an up and down direction duringrotation of the rear wheels. This rod strikes against a pad on the underside of the hinged seat and gives the seat an upward toss, which as therod moves downwardly permits the seat to drop to its lower level. Thusthe child astride the push car is bounced up and down as he rides histoy horse and experiences the sensation of horseback riding.

In the drawings; Fig. 1 is a side elevation of the push ear showing thehinged seat in the maximum raised position. Fig. 2 is a sectional viewtaken along the line IT1I Fig. 1 looking in the direction of the ar--the line III Fig. 2, showing the driven rod at the bottom of its strokemovement, the dotted lines indicating the side limits of the sweep of.the rod under crank actuated movements. Fig. 1 is a side view of thecrank shaft axle, the paired connecting rods, the forward crank shaftand upright rod, as seen in Fig. 1 with the rear wheels and the righthand braces and frame supporting members removed for clearness ofillustration. Fig. 5 is an elevation of the main driw ing crank shaft.Fig. 6 is an elevation of the driven forward crank shaft. -Fig. 7 is aside view of the driven rod as actuated by an alternate gear drivenmechanism.

main body frame member preferably a wooden slab 10 is supported at therear by an inverted U-shapcd strap iron member having legs 11 11connected by a base portion 11 A pair of inclined braces 12 and 12 leadfrom the bottom of the legs 11 and 11 and attach to the under side ofthe forward portion of the member 10 at 13. An axle 1ft having a pair ofU-shaped bends 15 and 16 preferably positioned at 90 apart as seen inFig. 4, has itsouter ends housed as at 17 in holes through the leg andbrace elements and in which holes as bearings, said axle is adapted torotate. A pair of wheels 18 and 19 are rigid with the shaft 14 at itsopposite ends, as in Fig. 2.

At 20 is a vertical member, which in its preferred form will befashioned something like the head 21 of a horse having a neck portion22. A wheel 23 is rotatable on its axle being arranged within the sideplates or forks 24 which rigidly depend from the forequarter of themember 20. At 26 the neck portion is cut away to support and receive theforward end of the member 10. The bolt 27 passes through the member 10to engage the base 28 of the slot 26. Thus there is a pivoted steeringconnection at 27 between the members 10 and 20 as will be 35 readilyunderstood, or so that the horses head may be turned to either side.Outwardly projecting from the axle of the wheel 23 are foot supports 29,29, while handles like 30 project from either side of the head The seat31 for the child, covers the member 10 and is hinged thereto at 32behind the pivoted connection 27. A bolt 33 having a head 34L isattached and suspended from the under central portion of the seat 31,passing through an opening or slot guide 35 in the member 10. In theview Fig. 1 the head 34 contacts the base member 10 thus limit ing theupward toss of the hinged seat 31.

At 36 is a block secured to the underside of the member 10 or so as tothicken the member 10 at that point. Slots 37 and 3'? through themembers 10 and 36 pass the rod 38. At 39 is a pad or plate atfixedto theunder side of the seat 31 and against which the end of the rod 38strikes as later explained.

A second crank shaft 40 has its opposite ends housed to rotate in holesprovided in the braces 12, 12; this shaft 10 is positioned above andforward of the axle 14 and carries a pair of U-shaped bends and 12,preferably positioned an angle of 90 with respect to each other, whilean intermediate U-shaped bend i-s'shown at- 13 positioned at an acuteangle with respect to crank ll and an obtuse angle with respect to crankThelower hooked end of the rod 38 engages the crank 4:3. The lowerhooked end 1% may be formed similar to a connecting rod hearing if sodesired. Connecting". rods 45 and 46' connect cranks 10%2 and 15- 41.
